WORLD'S BEST MARBLE RUN!!! (70,000 Pieces) - Marble World

This could be the BIGGEST and BEST Marble Run in the WORLD! Enjoy a tour through this INCREDIBLE creation. It took over 1 year to build and consists of around 70,000 pieces. We have never seen anything like this before. Built by Formula H67, a very talented regular viewer of my YouTube channel. I was first told about this marble run long before its release, and have been excitedly waiting to make a video to showcase it ever since. Prepare to have your mind blown! I hope you all enjoy the video :) LINK to the MARBLE RUN featured in this video: Marble Valley by Formula H67 https://steamcommunity.com/sharedfile... This Marble run is extremely demanding, even on powerful computers. It may also take a long time to load up initially... 8m 26s for me. However if you can handle it, download it and check it out with the link above. You won't be disappointed! SUBSCRIBE, Smash The LIKE Button and Hit the BELL if you enjoy this video and want to see more on my channel! Thank you!!!
